About this licence
Microsoft Exchange Server 2016 Enterprise – Full On-Premises Control for Demanding Messaging Environments
Microsoft Exchange Server 2016 Enterprise is a full, perpetual retail license for organisations that refuse to compromise on control, compliance, or capacity. This is the definitive on-premises email, calendaring, and collaboration platform, engineered for IT teams who need to manage large-scale mail storage, enforce granular retention policies, and maintain service continuity through native high availability — all without recurring cloud subscription fees. Unlike the Standard edition, Exchange 2016 Enterprise removes database limits entirely, supporting up to 50 mounted databases per server and effectively unlimited storage growth. It is the strategic choice for enterprises, compliance-heavy sectors, and managed service providers who require a transferable, volume-independent license that they own outright. With Lizensa, you receive a genuine Microsoft retail key, verified installation media, and a VAT invoice, delivered digitally within minutes so your infrastructure project can move forward without delay.
Key features and benefits
Unlimited mailbox databases for unrestricted growth: Deploy up to 50 databases per server, eliminating the 5-database ceiling of the Standard edition. This allows you to segment large user populations, isolate high-risk departments, and scale archive mailboxes without architectural roadblocks.
Database Availability Groups for built-in resilience: Configure automatic database-level failover across up to 16 Exchange servers. If a server, disk, or even an entire site fails, mailbox access fails over seamlessly, minimising downtime and protecting your service-level agreements.
Advanced compliance and eDiscovery tools: Apply In-Place Hold and Litigation Hold to preserve mailbox content for legal or regulatory investigations. Run delegated eDiscovery searches across the organisation directly from the Exchange admin centre, reducing reliance on third-party tools.
Integrated Data Loss Prevention: Use built-in DLP policies to identify, monitor, and automatically protect sensitive information such as financial data, national ID numbers, or health records. Prevent accidental leaks before they happen with transport rule actions and user notifications.
Improved Outlook on the web experience: Users get a clean, touch-optimised web client with inline previews, pinned favourites, and a modern attachment workflow that links to cloud storage instead of sending bulky files, improving productivity on any device.
Simplified architecture and management: The co-located mailbox and client access roles reduce server footprint and complexity. Manage your entire environment through a single, web-based Exchange admin centre that loads faster and exposes more controls than its 2013 predecessor.

Perpetual retail licensing with transfer rights: This is a full, permanent license, not a subscription. You can reassign it to a different server if hardware changes, or resell it entirely — a flexibility that OEM and volume licensing models often restrict.
Hybrid-ready for staged cloud migration: Exchange 2016 supports hybrid deployments with Microsoft 365, enabling a phased move to the cloud while maintaining on-premises control. Use the Hybrid Configuration Wizard for guided setup and unified mailbox management.
64-bit server architecture with 16 GB recommended RAM: Built exclusively for 64-bit Windows Server, the platform uses large memory caches to reduce disk I/O and improve search performance, making it responsive even with thousands of concurrent connections.
What's included with your purchase
When you buy Microsoft Exchange Server 2016 Enterprise from Lizensa, you receive a complete, activation-ready package. Your order confirmation email contains a unique product key for a full Retail license, along with a secure download link for the official Microsoft installation media. This is a perpetual license — you pay once and own it indefinitely, with no expiry date and no mandatory renewal fees. A detailed activation guide walks you through the installation process, and a VAT-compliant invoice is provided immediately for your accounting records. The license is transferable, meaning you can move it to new hardware or resell it in accordance with Microsoft's retail terms. Please note that this purchase covers the server license only; each user or device accessing Exchange requires a separate Client Access License, which Lizensa can also supply.
Licensing explained: what you need to know
Exchange Server 2016 follows a server-plus-CAL licensing model. The server license you purchase here grants you the right to install and run Exchange Server 2016 Enterprise on one physical or virtual server. However, to access the server — whether to send email, book a meeting, or view a shared calendar — every user or device must be covered by a valid Exchange Server Client Access License. You can choose between User CALs, which license a specific person to access Exchange from multiple devices, or Device CALs, which license a single device that may be used by multiple people. This model gives you flexibility to match your organisation's work patterns.
This Enterprise edition includes full virtualization rights: you may run the software in a virtual environment on servers you control. Compared to the Standard edition, which limits you to five mounted databases, Enterprise is designed for scale, supporting up to 50 databases per server and enabling advanced features like In-Place Hold and unlimited archive mailboxes. If you are migrating from an older version, note that Exchange 2016 does not support in-place upgrades from Exchange 2013 or 2010; a new server installation and mailbox migration is required.
System requirements and compatibility
Exchange Server 2016 Enterprise is a 64-bit server application that must be installed on a supported Windows Server operating system. Microsoft officially supports deployment on Windows Server 2016 and Windows Server 2012 R2. The minimum hardware specification calls for 4 GB of RAM and 32 GB of free disk space, but for production environments, Lizensa strongly recommends at least 16 GB of RAM and a storage layout designed for Exchange's I/O patterns. The system requires internet connectivity for product activation and for certain features like the Hybrid Configuration Wizard. This product supports multiple interface languages, including English, German, French, Dutch, and Polish, allowing your administrators to manage the server in their preferred language. Because exact requirements can vary with cumulative updates and specific server roles, we recommend validating your deployment plan against Microsoft's current technical documentation before beginning installation.
Installation and activation
After your purchase is completed, Lizensa delivers your license key and a download link for the installation media to your email inbox, typically within seconds. You can also access them anytime from your customer account on our website. Installation follows a straightforward process: download the ISO file, mount it on your Windows Server, and run the Exchange Setup wizard. When prompted, enter the product key you received. The server will then contact Microsoft's activation service over the internet to validate and activate your license. If your server does not have direct internet access, a volume activation method may be required, but this retail key is designed for online activation. Should you encounter any errors during setup or activation, our support team is available to help troubleshoot. Because this is a perpetual retail license, you are entitled to reinstall and reactivate the software on the same or replacement hardware, provided the license is removed from the previous server.

FAQ — frequently asked questions
Is this a subscription or a one-time purchase?
This is a one-time, perpetual license. You pay a single price and own the right to use Microsoft Exchange Server 2016 Enterprise indefinitely. There are no monthly or annual fees for the server license itself.
What is the difference between a Retail license and an OEM license?
A Retail license, like this one, is transferable: you can move it to a different server if your hardware changes, and you can resell it. An OEM license is typically pre-installed on a new server and is locked to that specific machine for its lifetime, offering no transfer rights.
How fast will I get my license key after ordering?
Our digital delivery system sends your license key and download link to your email address within seconds of a successful payment. You can also find them immediately in your Lizensa customer account.
Is this a genuine, legal Microsoft license?
Absolutely. Every license Lizensa sells is sourced from authorised European distributors and passes Microsoft's online activation and validation checks. You receive a legitimate product key and a VAT invoice for your records.
What if I have trouble activating the license?
Our free multilingual support team is ready to help. If you encounter an activation error, contact us with the error code and we will guide you through resolution, whether it requires a phone activation or troubleshooting your server's configuration.
Can I reinstall or transfer this license to another server?
Yes. As a Retail license, you can uninstall Exchange from one server and reinstall it on another. The license must only be in active use on one server at a time. This flexibility is a key advantage over OEM licensing.
Does this license work in my country?
This license is valid for activation and use in all 27 EU member states and beyond. It is not region-locked to a specific country, making it suitable for pan-European organisations.
What payment methods does Lizensa accept?
We accept payment via credit and debit cards, SEPA bank transfer, iDEAL, BLIK, and Google Pay. All transactions are processed securely through Stripe, a certified Level 1 PCI Service Provider.
Do you provide a VAT invoice?
Yes, a VAT-compliant invoice is generated automatically with every purchase and delivered alongside your license key. For B2B customers in the EU, reverse-charge VAT rules can be applied where applicable.
What is your refund policy?
You have a 14-day right of withdrawal under EU consumer protection law. If the license key has not been activated or used, we will issue a full refund. Our support team can verify the key's status if you are unsure.
Do I need anything else to use Exchange Server 2016 Enterprise?
Yes. In addition to this server license, you must purchase Exchange Server Client Access Licenses for every user or device that will access the server. Without the correct number of CALs, your deployment is not compliant with Microsoft's licensing terms.
Can I use this license to upgrade from an older version of Exchange?
This license is for a new installation of Exchange 2016. Microsoft does not support an in-place operating system or application upgrade from Exchange 2013 or 2010. You will need to install Exchange 2016 on a fresh server and migrate your mailboxes to it.
